I saw this advice on another forum and wanted to share it with everyone on this thread. It's about what to do when considering a new purchase:
"Here is my advice, put the money to one side and look at watches. Once you set your heart on one then try your best to leave it for two weeks before you buy. If in two weeks time you have changed your mind and have your eye on something else or you have gone a bit cold on the watch then repeat the process.
This process has saved me a fortune and a lot of hassle."
